May 23, 2017 — If you like lobster – and care about maintaining the fishery as both a cultural and economic resource in Maine – should you care what it ate before it made it to your plate?
Lobsters get a bad rap for being scavengers, says veterinarian scientist Robert C. Bayer, executive director of the University of Maine’s Lobster Institute in Orono. In fact, they have rather discerning chemosensory apparatus housed in the short antennae on their heads and tiny sensing hairs all over their bodies.
With a sense of smell more akin to a dog’s than a human’s, lobsters can sniff out a single amino acid that tags their favorite food. For Maine lobsters, that’s herring. So lobstermen favor it as bait up and down the coast.
In 2016 the state’s lobster fishery hit record numbers in volume (over 130 million pounds) and value ($530 million). With so many traps in play, herring became the second-most valuable fishery in Maine, weighing in at $19 million last year. The hike in its value corresponded with the demand from hungry lobsters just as there was a drop off in herring landings in New England.
Earlier this month, interstate marine fisheries regulators approved new rules to avoid another bait shortage. To space out the catch, herring fishermen are now subject to a weekly limit on the amount they can bring to shore. Bayer says it takes one pound of herring to produce one pound of lobster. That same input/output ratio, when used in fin fish aquaculture, has been rendered an unsustainable practice.
